To lll whom' it may concern.' A

Be it. known that I, EDGAR E. Gnnvaja citizen -of the United- States, residing at Bellevue, in' vthecounty of Allegheny and "State of Pennsylvania, have' invented Certain new and useful Improvements in v HoseCoupling Nozzles and- Clamps, of which the following' is a'specication. t.

The prime lobject of my invention is to provide a new and .improved hose coupling nozzleJ and clamp of a character particularly. designed for use inconnect'ion with a hosev adapted'to carry 'a' considerable fluid pressure, suchI for example, as a-hose. employed in connection with a 'rotary drilling apparatusemployed for drilling wells.

In the accompanying drawings, .which illustrate applications of my invention,

Figure 1 is apart side elevational and a lpart vertical sectional view of a hose nozzle and clamp embodying my invention;

Fig. 2 is a horizontal sectional aview, the section being taken on line 2-.2 of Fig. 1;

Fig. 3, a, part sectional view and -a -part l 25' elevational view, theV sectionbeing on a line ata fright angle to thefview of Fig. 1.; and

:Fig: 4:, a part vertical; sectional and a part elevational view of a modified Aform embody- 5 ed to beL entered in and secured to a pipe ing my invention. A. .Referring to the drawings, 1" designates.

v -a ,portion of the hose 'to which the nozzle and clamp are applied.A The' nozzle o f the form of Fig. 1 includes a 4portion 2, adapted to be entered, inthe hose; This portion`2at.

kone end, is' formed'with'anannularn flange or' enlargement 3', and at its'A opposite 'endwith aicoupling member 4. Between member 4 `'against which clamping pressure is exerted. i

andenlarg'ement 3, the nozzlel is formed with a smooth hose contacting surface .designed to make contact with that portion of the hose by the clamp. As illustrated,'member or portion is formed with an. annular flange anannularrecess 6,- and an -annular -5 iljange 7..

Disposed withinA th'oemdividednclamp Y84, I provide tapered; Nliose ing slips Aor slightlymovable wedge mem ers 9: adapted-.'- tomovej with the hose should any'slippin'g. of the hosejon the nozzle occur; two'. ofjthe'se' .members 9 are shown, and each is provided'jf with aserrated or corrugated hose gripping face 10, and with interlockii'ig or dove-tailed vertically'-` v`extending meetin edges 11. These interlocking edges of `t e hose grip- :i Specification of Letters Patent.

when the members are forced tightly into position by 'the action of the clamp 8.

The clamp 8, as illustrated and .as preferred, includes two similar partially encircling members a and b, each member having its interior face c tapered in an opposite direction from the taperof the lslips 9.

Each of the members is further formed with.l

apertured enlargements 12, through which boltsl 13 are passed, and with one or more lugs 14 adapted to be entered in recess 6 of' the coupling portion or end of the nozzle member.- 1

' It will be evident that .when the nuts 15 on the bolts 13 are tightened, the 'clamp will canse the members 9v tok tightly grip the hose section.A and rmly hold it' 'inthe desired position between' the 4outer face of the-nozzle and the serrated"face`s f the tapered slips,-

and, further, that theengaging lugs 14 will be, maintained in the recess 6.1L

y .In the'modiied orfn shown by Fi 4, the construction, with the exception of t ecoupling portion 4, is the same as the form of Fig. 1. .In this latter. construction, portion 4 is provided with a ythreaded end 5a adapt- -o'fgthe clamp, and that'by making that portion ofthe nozzle designed to be disposed within the clamp, with a smooth hose contacting surface, there 'willbe nothing to injure the hose when said movement occurs.
